Petro Poroshenko, the president of Ukraine who is currently dealing with an apparently Russian-backed insurgency in the east of his country, is expected to attend the meeting of the Nato-Ukraine commission on the afternoon of September 4.

The UN Secretary General has been invited and is expected to attend a meeting about Afghanistan on the afternoon of September 4. Enda Kenny, Prime Minister of Ireland, and Tony Abbot, Prime Minister of Australia, are also expected to attend the same meeting.

But Afghanistan’s own head of state, Hamid Karzai, has given the event the cold shoulder. He won’t be going because of disagreements with the US over Afghan security needs after troops leave in 2014.

The following is a list of countries invited and the heads of state and government that could be attending.
